Could you please try to configure you email client correctly? It's
rather confusing the "regards, Manish Jaggi" at the beginning of the mail.

Did you read the comment explaining the structure arm_smmu_xen_device?
It's just above the definition.

"arm_smmu" is the prefix for any structure within this file.
"xen" means it's a structure added for Xen.
"device" means it's data stored for a device.

I won't choose a name myself for a name that I think valid...

If you really want to change the name, you have to put at least
arm_smmu_xen_ in the name.
